Description

Technical Field

[0001] The present invention relates to the technical field of belt coal conveying devices, and specifically relates to a belt coal conveying device with an anti-overflow and anti-scattering function. Background Technique

[0002] With the continuous development of the national economy, the development of coal energy has been increasing continuously. The transportation system for power plants to transport coal mines has changed greatly. The belt conveyor is one kind of coal conveying machinery in coal mines. Due to the limited space in power plants, with the improvement of coal mining mechanization and the acceleration of the working face progress, the quality of transportation equipment is a very important link. The belt conveyor has the advantages of long transportation distance, large transportation capacity, small working resistance, convenient installation, low power consumption, and less wear.

[0003] Currently, the transportation of coal blocks is usually completed through a belt coal conveying device. However, in the case of a large number of coal blocks, the stacking range of coal blocks on the belt will become larger. Since the inclination angle of the belt remains unchanged, the number of coal blocks stacked on the belt is limited. If the number of coal blocks exceeds a certain amount, it may cause the coal blocks to overflow and scatter from the belt during transportation. If the rotation speed of the belt is increased, it will cause the equipment to work under overload, resulting in a shorter service life of the equipment and affecting the transportation of coal blocks. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a belt coal conveying device with an anti-overflow and anti-scattering function, which solves the problem that if the number of coal blocks exceeds a certain amount, it may cause the coal blocks to overflow and scatter from the belt during transportation.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A belt coal conveying device with an anti-overflow and anti-scattering function includes a support platform. Two groups of limit grooves are opened on the support platform. Two groups of fixed columns are fixedly installed on each group of limit grooves. A limit baffle that is slidably connected to the fixed columns is slidably installed on each group of limit grooves. A blanking plate is rotatably installed on the support platform;

[0007] An adjusting device for preventing coal blocks from overflowing and scattering is installed on the support platform;

[0008] A flattening device for making the stacking of coal blocks more stable is installed on the support platform;

[0009] As the blanking plate rotates, the adjusting device is activated to drive the movement of the two limit baffles. The height of the flattening device is changed by the movement of the limit baffles.

[0010] Preferably, the adjusting device includes two groups of fixed shafts fixedly mounted on the blanking plate and rotatably connected to the support platform, a torsion spring is sleeved on each group of the fixed shafts, a No. 1 sprocket is fixedly mounted on each group of the fixed shafts, a chain is sleeved on each group of the No. 1 sprocket, two groups of threaded rods threadedly connected to the limit baffle are rotatably mounted on the support platform, a No. 2 sprocket is fixedly mounted on each group of the threaded rods, and the No. 2 sprocket is connected to the No. 1 sprocket through a chain transmission.

[0011] Preferably, the adjusting device also includes a plurality of groups of sliding grooves evenly opened on the limit baffle, each group of the sliding grooves is fixedly installed with a fixed rod, each group of the sliding grooves is slidably installed with a sliding block slidably connected to the fixed rod, a No. 1 support frame is rotatably installed on the sliding block, and a No. 1 rotating roller is rotatably installed on the No. 1 support frame.

[0012] Preferably, the adjustment device also includes a plurality of groups of No. 2 support frames which are evenly fixedly mounted on the support platform and rotatably connected to the No. 1 support frame, and a No. 2 rotating roller is rotatably mounted on each group of the No. 2 support frames.

[0013] Preferably, the flattening device comprises a fixing frame fixedly mounted on the supporting platform, a supporting plate is fixedly mounted on each group of the limit baffles, and a rotating plate is rotatably mounted on each group of the supporting plates.

[0014] Preferably, the flattening device further comprises a connecting plate rotatably mounted between the two sets of rotating plates, a pressing roller is rotatably mounted on the connecting plate, and two sets of limiting rods slidably connected to the fixing frame are fixedly mounted on the connecting plate.

[0016] Preferably, the support platform is provided with a feed port located above the blanking plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention pours coal through the feed port by setting an adjusting device. When there is a lot of coal, the blanking plate rotates to drive the two sets of limit baffles to move in the limit groove, and the angle between the two sides of the belt on the No. 1 roller and the No. 2 roller becomes larger, and the range of the bottom layer to accommodate coal blocks will also become larger, so that the belt can accommodate more coal blocks, avoiding the situation where the coal blocks may overflow from the belt during transportation if the number of coal blocks exceeds a large amount.

[0019] 2. Through the setting of the flattening device in the present invention, the connection roller is driven to move upward by the movement of the limit baffle, and the coal at the higher position on the belt is pressed into the coal pile by the connection roller, making its structure stable. When there is more coal, since the stacking area at the bottom of the coal increases, the limit height for coal stacking is increased, resulting in a larger transportation volume of coal, and avoiding the situation where coal blocks at the higher position may roll off the belt in case of transportation bumps.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will describe in detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0026] Embodiment 1

[0027] Since the inclination angle of the belt remains unchanged, the number of coal blocks stacked on the belt is limited. If the number of coal blocks exceeds a certain amount, it may cause the coal blocks to spill from the belt during transportation. To solve this problem, refer to Figures 1 - 3, in this embodiment, a belt coal conveying device with an anti-spillage function is proposed, which includes a support table 1. Two groups of limit grooves 101 are provided on the support table 1. Two groups of fixed columns 102 are fixedly installed on each group of limit grooves 101. A limit baffle 103 slidably connected to the fixed columns 102 is slidably installed on each group of limit grooves 101. The fixed columns 102 make the movement of the limit baffle 103 more stable. A blanking plate 104 is rotatably installed on the support table 1. A motor 4 is fixedly installed on the support table 1. The output end of the motor 4 is rotatably installed with a driving roller 401 rotatably connected to the support table 1. The driving roller 401 is driven to rotate by the motor 4, so as to drive the belt to rotate. A connecting roller 402 is rotatably installed on the support table 1. The driving roller 401, the connecting roller 402, the first rotating roller 211 and the second rotating roller 213 are connected by belt drive. An inlet 5 located above the blanking plate 104 is provided on the support table 1 for feeding coal lumps.

[0028] An adjusting device 2 for preventing coal blocks from overflowing and spilling is installed on the supporting platform 1. The adjusting device 2 includes two groups of fixed shafts 201 fixedly installed on the blanking plate 104 and rotatably connected to the supporting platform 1. A torsion spring 202 is sleeved on each group of fixed shafts 201, so that the blanking plate 104 can quickly reset. A first sprocket 203 is fixedly installed on each group of fixed shafts 201. A chain 204 is sleeved on each group of first sprockets 203. Two groups of threaded rods 205 rotatably installed on the supporting platform 1 and threadedly connected to the limit baffle 103 are provided. A second sprocket 206 is fixedly installed on each group of threaded rods 205, and the second sprocket 206 is drivingly connected to the first sprocket 203 through the chain 204. The adjusting device 2 further includes a plurality of sliding grooves 207 uniformly formed on the limit baffle 103. A fixed rod 208 is fixedly installed on each group of sliding grooves 207. A sliding block 209 slidably connected to the fixed rod 208 is slidably installed on each group of sliding grooves 207. The fixed rod 208 makes the sliding block 209 move more stably. A first support frame 210 is rotatably installed on the sliding block 209. A first roller 211 is rotatably installed on the first support frame 210. The adjusting device 2 further includes a plurality of second support frames 212 uniformly fixedly installed on the supporting platform 1 and rotatably connected to the first support frame 210. A second roller 213 is rotatably installed on each group of second support frames 212. Coal is poured through the feed inlet 5, and the coal falls onto the belt after being buffered by the blanking plate 104. When there is more coal, the amount of coal on the blanking plate 104 also increases. The increased weight borne by the blanking plate 104 causes the blanking plate 104 to rotate. The rotation of the blanking plate 104 drives the first sprocket 203 connected to the fixed shaft 201 to rotate. Under the action of the chain 204, the rotation of the first sprocket 203 drives the threaded rod 205 connected to the second sprocket 206 to rotate within the limit baffle 103, causing the two groups of limit baffles 103 to move within the limit slots 101. The movement of the limit baffle 103 causes rotation between the first support frame 210, the sliding block 209 and the second support frame 212. The sliding block 209 moves downward within the sliding groove 207, increasing the included angle between the two sides of the belt on the first roller 211 and the second roller 213. The range for accommodating coal blocks at the bottom layer also becomes larger, enabling the belt to accommodate more coal blocks, and avoiding the situation where if the number of coal blocks exceeds a certain amount, the coal blocks may spill off the belt during transportation.

[0029] Embodiment 2

[0030] Since when there are more coal blocks, the height of the coal blocks piled up on the belt will become higher, and if there is transportation jolting, the coal blocks at the higher position may roll off the belt. To solve this problem, referring to Figures 1 - 3, a flattening device 3 for making the stacked coal blocks more stable is installed on the support table 1. The flattening device 3 includes a fixed frame 301 fixedly installed on the support table 1. A support plate 302 is fixedly installed on each group of limit baffles 103. A rotating plate 303 is rotatably installed on each group of support plates 302. The flattening device 3 further includes a connecting plate 304 rotatably installed between the two rotating plates 303. A pressing roller 305 is rotatably installed on the connecting plate 304. Two limiting rods 306 fixedly installed on the connecting plate 304 and slidably connected to the fixed frame 301 are provided to make the movement of the connecting plate 304 more stable. When the distance between the two limit baffles 103 becomes larger, the movement of the limit baffle 103 drives the movement of the support plate 302, and the movement of the support plate 302 drives the movement of the rotating plate 303, causing rotation between the rotating plate 303, the connecting plate 304 and the support plate 302. The rotating plate 303 drives the connecting roller 402 connected to the support plate 302 to move upward, and presses the coal at the higher position on the belt into the coal pile through the connecting roller 402 to make its structure stable. When there is more coal, due to the increase in the stacking area at the bottom of the coal, the limiting height of the coal stacking is increased, so that the transportation volume of the coal becomes larger, avoiding the situation that the coal blocks at the higher position may roll out of the belt in case of transportation bumps.

[0031] Working principle: Coal is poured through the feeding port 5, and the coal falls onto the belt after being buffered by the blanking plate 104. When there is more coal, more coal will also fall on the blanking plate 104, and the increased weight borne by the blanking plate 104 causes the blanking plate 104 to rotate. The rotation of the blanking plate 104 drives the rotation of the first sprocket 203 connected to the fixed shaft 201. Under the action of the chain 204, the rotation of the first sprocket 203 drives the threaded rod 205 connected to the second sprocket 206 to rotate within the limit baffle 103, causing the two limit baffles 103 to move within the limit groove 101. The movement of the limit baffle 103 causes rotation between the first support frame 210, the sliding block 209 and the second support frame 212. The sliding block 209 moves downward within the sliding groove 207, increasing the included angle between the two sides of the belt on the first roller 211 and the second roller 213. When the distance between the two limit baffles 103 becomes larger, the movement of the limit baffle 103 drives the movement of the support plate 302, and the movement of the support plate 302 drives the movement of the rotating plate 303, causing rotation between the rotating plate 303, the connecting plate 304 and the support plate 302. The rotating plate 303 drives the connecting roller 402 connected to the support plate 302 to move upward, and presses the coal at the higher position on the belt into the coal pile through the connecting roller 402.
